I just checked out the puppetlabs.com link. Looks like very helpful software
and I see that it runs on Ubuntu.
I am going to investigate that further and will most likely try it out.
I try to keep the environment as consistent as possible with Ubuntu being
the standard for our servers.
I had found that when the local_interfaces line was left as the default
setting (i.e., MAIN_LOCAL_INTERFACES not set), 127.0.0.1 was being excluded
in the output when doing netstat -plant.
I need 127.0.0.1 and I therefore have been setting MAIN_LOCAL_INTERFACES in
/etc/exim4/exim4.conf.template.
However, during my trial and error activities today, I realized that when
MAIN_LOCAL_INTERFACES is not set or is improperly set, then
/var/lib/exim4/config.autogenerated was setting local_interfaces to the
value of dc_local_interfaces in /etc/exim4/update-exim4.conf.conf which I
had configured to 192.168.121.123 but had not included 127.0.0.1. I
therefore just commented out dc_local_interfaces at this point because I am
using your ".include" solution and it is now working.
Thanks again.

No problem.
I think in general you have been confusing things like lookups, which
can look in files, with the more generic facility. Unsurprisingly
.include is mentioned in the documentation, but of course you have to
know something like that is there :-)
For configuration management many people like puppet
http://www.puppetlabs.com/puppet/introduction/
I find that if you have an environment where all the machines are the
same distribution you're better off using something like a private
repository to publish your data, but in a mixed environment puppet is
ideal. It will definitely allow you to publish a machine-specific
customised config for exim :-)
On the other hand, you could just let exim listen on all interfaces,
unless there were a good reason not to (i.e. multiple other interfaces
which must not be running SMTP) - just don't use a local_interfaces line
at all and exim listens to *:25 by default.
